Is rustic or UrBackup better?

Neither clearly leads. rustic starts at Free and UrBackup at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, rustic or UrBackup?

rustic starts at Free and UrBackup at Free.

Does rustic or UrBackup run on more platforms?

rustic runs on Linux, macOS, Windows. UrBackup runs on Linux, Windows, macOS, FreeBSD.

Can I use rustic for free?

Both have a free tier, so you can try either at no cost before committing.

What is rustic best used for?

rustic is most often used for an existing restic user who wants configuration files rather than long command lines in cron, backing up a memory constrained machine where the reference implementation is uncomfortably heavy, writing to append only or cold object storage where the default tooling assumes rewritable buckets, keeping a second implementation available so a long lived archive does not depend on one codebase. Of those, an existing restic user who wants configuration files rather than long command lines in cron and backing up a memory constrained machine where the reference implementation is uncomfortably heavy are not what UrBackup is typically brought in for.

What can rustic do that UrBackup cannot?

rustic covers restic format compatibility, Configuration profiles, Deduplicated encrypted backups, Cold and append only storage support. UrBackup covers Windows image backups, File backups, Web interface, Client discovery.

The short version

Each has a real cost: rustic the project is small with a short list of active maintainers, so bus factor is a genuine consideration for software whose job is to still work in five years.; UrBackup backups are stored on the server without encryption at rest by default, so the backup server holds a readable copy of every machine it protects and becomes the highest value target on the network.
They diverge on capability: rustic covers restic format compatibility, UrBackup covers Windows image backups.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

rustic

The project is small with a short list of active maintainers, so bus factor is a genuine consideration for software whose job is to still work in five years.
It inherits the restic repository format, so design limits in that format, including the cost of pruning large repositories, are inherited rather than fixed.
Command names, flags and behaviour do not map one to one onto restic, so scripts and runbooks need rewriting rather than a binary swap.
Far fewer people have performed a real restore from it under pressure, and backup software is one of the few categories where being second most used is itself a risk.
Alternating between rustic and restic against one repository works but doubles the surface for a version incompatibility to corrupt state, so most operators should pick one and stay with it.

UrBackup

Backups are stored on the server without encryption at rest by default, so the backup server holds a readable copy of every machine it protects and becomes the highest value target on the network.
Deduplication relies on filesystem features such as hard links, btrfs or ZFS, so a server built on the wrong filesystem silently consumes far more space and the fix is a rebuild rather than a setting.
There is no native object storage target, so offsite copies mean replicating the server storage with another tool rather than backing up to a bucket directly.
Restoring a full Windows image requires booting a restore environment, which is a manual, on site procedure that needs to be rehearsed before the day it is needed.
A single server holds everything and there is no built in clustering, so its own failure removes every recovery point at once unless you have separately solved replication.

Answered from the vendors’ own pages

rustic: Can it read my existing restic repository?

Yes, that is the point of the project. Take a copy and verify before you rely on it, as with any change to backup tooling.

UrBackup: Does it back up Linux servers as well?

File backups yes, image backups no. The image path is Windows only through volume shadow copy.

rustic: Should I switch from restic?

Only for a specific reason such as configuration profiles, memory use or cold storage handling. Compatibility means there is no cost to trying and no cost to going back.

UrBackup: Is the data encrypted?

Transport can be encrypted, and there is optional client side file encryption, but the default server storage is not encrypted at rest. Use full disk encryption on the server.

rustic: Is it production ready?

It is used in production by a small community, but it is younger and less exercised than the implementation it is compatible with. Test restores accordingly.

UrBackup: Can I back up to Amazon S3?

Not directly. The server writes to local or mounted storage, so cloud copies are made by replicating that storage separately.

rustic: Does it support the same back ends?

The common ones, including local, SFTP, S3 compatible storage and rclone. Check the current list before committing to an unusual target.

UrBackup: How many clients can one server handle?

Dozens is routine on decent hardware. The limit is usually storage input and output during overlapping backup windows rather than client count.
