    Re: RAID-1 for existing development server

    If you use LVM, then it is possible to quiesce the DB storage using LVM snapshots, then take the backup of the snapshot. LVM has the ability to provide RAID, if the PV/VG and LV are setup on...
  2. [ubuntu] Re: Repair corrupt filesystem using fsck on CF

    Sorry - I didn't remember the CF part. You may be stuck. Hopefully, you made a ddrescue copy before doing anything else. Flash media wears out in different ways. Parts become unreadable, then...
  3. Re: CryptData's enforced password key; so secure, you can't change it!

    There is some usability issue with PopOS? Something about encryption? Encryption is never easy, anywhere. The way that encryption works on my laptop is the same way that it works on Android and...

    smartctl has many options which are documented in the manpage.

  5. Re: Timeshift [rsync]: wrong disk usage reporting (just for information)

    Some file systems lie about the true available storage. df -Th would show the file systems too.

    Sorry, I don't use timeshift, so cannot comment on that tool.

    Re: Differences in BASH in last decade

    Re: How can I restore my backups on my VPS?

    Well ... sorta. Sometimes, I restore my backups by booting a VM off an ISO (Ubuntu-mate iso) and use it to restore files from my backup tool. Fixing boot issues using an install-ISO is how I do...

    Re: How can I restore my backups on my VPS?

    It depends on what the tar includes, and how the VPS boots.
    Tar was designed for MB-sized backups, not GB. Best to use a better backup tool or just pay the VPS to handle it for you.

    On a VPS, it...

    True. Nominally, someone showing up using sed has a level of expertise, especially with file redirection.

  13. Re: How do I install Ubuntu in Windows 10 which ntfs ?

    Re: RAID-1 for existing development server

    First, how are your system and data backups? If the backups are 100% perfect, know-you-can-restore, then you aren't ready for RAID. RAID solves 2 problems. Backups solve 1001 problems, including a...

    Re: sed scalability

    To do many files, find and xargs is the common way.
    I would use grep -v instead, if sed performance was an issue. fgrep works with fixed strings, not regex, which should be faster.
